How to dispose CrossMediaManager properly?

I'm playing an HLS content on CrossMediaManager. When users press back, I'm trying to dispose the player, but the player is still playing, I can see it's running on notification drawer and I can listen to video. Here is the code I've tried.
`VideoPlayer` is the Reference name of the `VideoView`

```
protected override void OnDisappearing()
{
base.OnDisappearing();
CrossMediaManager.Current.Dispose();
VideoPlayer.Dispose();
}

Start with the OnDisappearing example using CrossMediaManager.Current.Dispose() and VideoPlayer.Dispose(), then trace the CrossMediaManager lifecycle for HLS playback when navigating back. Reproduce the issue and verify that playback stops and the notification drawer no longer exposes active media afterward.
